What is the accuracy ?? For example if you were to measure a known distance of exactly 100 ft, what would be the error ??

Patricia, the wheel itself is very accurate, I've tested many of these at the factory and they all came in within and inch or two over 100ft. The errors you will have though will be from your surface or not judging the starting point and finish point accurately.

I don't know how much you have been involved in "accurate measurement,?"They have been doing this to our propertyfor quite a while.Your measure is going to be more close, I promise you!

Less than an inch. It's very accurate and if you can use it, well worth the money.

Ive had this range finder for 3 years now. It is deadly accurate. Make sure your hitting the pin and its dead on. If the GPS next to you gives a different reading it is wrong. I have had that come up several times. I trust the laser in my hand over the satellite 12000 miles away. If I check GPS locator on my smartphone its never dead on. Misses by 30 feet (10 yards) sometimes.

It is not very accurate and it basically has to be in view of the motion sensor. It won't work thru walls and it has a range of about 30 to 50 feet

YES, I tested the unit I have & The Max I could read was 102 foot. It is almost impossible to see the laser dot at that distance anyway.

It is very accurate. Just make sure you get one in the correct range you need. I may need another one due to this fact. The levels I check are at the very top of the range of the refractometer i bought.

It wouldn't be 100% accurate, but close. My guess is the reading would be about 25-50% low.

I Have not tested with 50 feet. But in general the bigger the distance the bigger the area you are sampling, and therefore less the precision. I would have it's best used at about 25 feet and under. At 50 feet you are sampling 4.2 inches diameter.

I'm not aware of a calibration function to it. It's simply quite accurate out of the package.

At that range it's not very accurate.....you better off with the gamo pt -85 accurate at that range.

It works off of GPS, so it is as accurate as your Garmin in your car. I'm guessing plus or minus 20'. The altitudes it gives you are just like an altimeter on a plane, above mean sea level. You would need radar to get altitude referenced to ground, not included.

Make sure you are not picking up something behind the target. I have never had any accuracy problems with mine. Also, how do you know that it is 100 instead of 90? This model doesn't have gps btw.

2 meters -3 meters distance, more accurate. If the distance is far, cannot guarantee the accuracy of the.

Overall a good product but certainly will not work the distance advertised. I didn't do any exact experiments but 500 ft would be my estimate for reliable performance

Remember that this device calculates distance based on ball speed and trajectory (launch angle) through the use of doppler radar. The launch angle is pre-determined by inputting tour club selection (trajectory if loft angle of thr club) so if you typically have a lower or higher ball flight, then this is not very accurate at all. In fact, no one has the same trajectory everytime they hit a ball, so my answer is no...not very accurate. I sold mine and bought a laser. I get much more use out of a laser, especially on the course. True launch monitors, like Trackman, calculate distance using true ball speed, trajectory, and spin. You cannot get feedback like that out of a $200 device. Remember that this device calculates distance based on ball speed and trajectory (launch angle) through the use of doppler radar.

I'm sure this won't the answer you're looking for, but I've been as far away as about 6' ft and it worked. I've never tested to see how far away it works, though.

Haven't tested it for accurate distance but I am.pretty sure you can get 100 yards out of it. It also has a large spread so the darker the area the more you.can.light up. Be aware this uses D cell batteries.

I have not checked its accuracy against other thermometers. I do know the unit functions well and i have had no issues with it. I use it to switch on and off an incondesant light bulb that heats a small space where a control unit for a lumber kiln is. The manufacturer recommends that it not be exposed to temperatures less than 40 degrees. So right now, it is not doing anything but reading a fairly high temp and keeping the circuit open.
